Patent

CA 2478035

By injecting noise into drive electronics, the start time of the MEMS gyroscope may be improved. A noise source is used to provide bandwidth limited white noise with a bandwidth centered substantially at the tuning fork frequency of at least one proof mass.

La présente invention concerne un procédé consistant à injecter un bruit dans une électronique de commande afin d'améliorer le temps de démarrage du gyroscope à MEMS. Une source de bruit est utilisée pour fournir un bruit blanc à largeur de bande limitée présentant une largeur de bande centrée essentiellement sur la fréquence du diapason d'au moins une masse étalon.
